Marketplace Integration Specifics

Expanding online brand presence and targeting potential e-retailer clients is one of the biggest concerns for eCommerce software vendors in 2022. Therefore, the development of eCommerce marketplace integration is one of the best ways for them to start selling their solutions to e-store owners from different countries and increase the market share as soon as possible.

Sighting the immense opportunity, several eCommerce software vendors offer different solutions like inventory management software, accounting software, shipping management software, etc. For such vendors, it becomes necessary to integrate their solutions with each of the online marketplaces where their prospective clients have listed their online stores.

The list of the most popular and widespread marketplaces includes Amazon, eBay, Etsy, and Walmart.

They have their own Application Programming Interfaces or APIs, making integrations much more manageable. Integrations completed using such APIs enable to easily access e-store information related to orders, products, categories, customers, shipments, etc., from the marketplaces.

Steps That are Needed to Follow to Integrate With eCommerce Marketplaces

By now, you might have become interested in eCommerce marketplace integration. For example, suppose you are a SaaS vendor who intends to integrate your software solution with multiple online marketplaces. In that case, you should understand that this is a complex task, and the procedure requires expertise.

Step 1: Understand the API Documentation and specific features of a marketplace

As mentioned before, every popular eCommerce marketplace today has its own API along with bespoke documentation. That is why it is needed to understand how the API system for a particular marketplace works, and how does the documentation provide scope for integrating your software solutions with it.

Step 2: Making a choice

The integration can work out in multiple ways. The first option is where a team of advanced developers can be hired to establish integrations with all the marketplaces needed manually and one by one. The second solution is to use a third-party integration service like API2Cart that allows connecting any software with multiple marketplaces and shopping platforms at once, without the need to spend heavily on a team of developers.

Step 3: Data transfer

Once the connection is established, it is time to transfer essential data between the software and the eCommerce marketplace. The kind of information that can be transferred includes customer information, shipment records, order details, product lists, etc. With access to such data, software solutions can perform their functions and be useful for e-retailers who sell their goods on marketplaces.

Step 4: Maintenance and monitoring

Be it through a third-party service or in-house developers, there is a need for constant monitoring and maintenance of the marketplace integrations established.

Major Benefits of Integrating With eCommerce Marketplaces

There are multiple high-value reasons why your software company should invest in eCommerce marketplace integration development in 2022:

1. Smooth Data Flow

Any software solution relies on the data that it gets to work upon. By integrating your software with the eCommerce marketplace on which your clients list their stores, your system can easily access all the required information.

A straightforward data flow gets created wherein information like customer data, order details, product lists, inventory information, etc., gets passed down to your software for processing continuously. This helps keep your e-retailers ahead of the competition, making your solution more imperative for them.

2. Real-Time Updates

Real-time updates add dynamism to the business operations by allowing any real-time addition or deletion in inventory, orders, shipment details, etc., to be reflected at your end continuously.

You get to cater to the changing needs of your clients. This way, seamless integration makes your software solutions indispensable for the clients.

3. Easy Expansion

By integrating with multiple popular eCommerce marketplaces, you will emerge as a software service provider offering an all-encompassing solution. Also, your software will be recognized by various e-retailers on the market, giving you the exposure you need to expand your business. Once your solution gains wide acceptance, it will be easier for you to increase your market share and attract more clients.

Easy Way to Develop Multiple Marketplace Integrations

We’ve already mentioned the possible ways by which you can integrate your software with the multiple eCommerce marketplaces that are used by e-retailers. The more complex method to go about this is to hire a team of advanced developers who can manually establish these endpoint connections.

Given the complexity involved in this procedure, the costs of hiring IT professionals and making them do this job can be too expensive and challenging.

Contrary to this, there are options for going with a unified API like API2Cart.

API2Cart offers one API that allows you to integrate your eCommerce software with 40+ marketplaces and shopping platforms easily. It will be possible for your solution to be connected with Amazon, eBay, Etsy, and Walmart immediately. Further, the maintenance and monitoring of the Integrations are also supported.
